TPA3100D2PHPRG4

Overview

The TPA3100D2PHPRG4 is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 21.8 W of output power per channel into an 8-ohm load. The device operates within a supply voltage range of 10 V to 26 V and features a fixed gain of 36 dB. Total Harmonic Distortion plus Noise (THD+N) is specified at 0.11%. It utilizes a differential input type and provides differential outputs. The component is housed in a 48-pin HTQFP package with dimensions of 7x7 mm. It supports surface mount installation and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Stereo Class-D architecture providing high-efficiency audio amplification
• Integrated protection mechanisms including thermal shutdown and short-circuit protection
• Supports analog differential inputs for noise immunity
• Includes mute and shutdown control capabilities

Applications

• Portable media players and smartphones
• Tablets and handheld gaming devices
• Personal navigation systems
• Digital picture frames

Procurement Notes

Verify the specific suffix 'RG4' indicates RoHS compliance and green material status as defined by Texas Instruments standards. Confirm the package marking matches the 48-HTQFP physical dimensions. Ensure the ordering part number aligns with reel or cut tape availability requirements for automated assembly processes. Cross-reference the manufacturer date code to ensure component freshness and moisture sensitivity level integrity.

Selection Notes

Select this component when a compact stereo solution is required for battery-powered portable electronics. The fixed 36 dB gain simplifies system design by reducing external resistor networks. The wide supply voltage range allows compatibility with various battery configurations. Consider the thermal performance of the HTQFP package for enclosed designs requiring adequate heat dissipation pathways.

Part Context

This part belongs to the TPA3100D2 series, designed specifically for portable audio applications. It serves as a low-power alternative to higher-wattage industrial amplifiers. The RG4 suffix denotes environmental compliance. It competes in the market for small-form-factor audio solutions where efficiency and board space are critical constraints.

Replacement Considerations

The TPA3100D2PHP is a non-RoHS compliant equivalent with identical electrical specifications. The TPA3100D2PHPR offers the same functionality in a standard reel packaging format. Verify pin-to-pin compatibility and thermal characteristics when substituting these variants.
